Finnair was the least polluting of the world’s largest airlines in 2014, according to a new study, which also revealed that airlines had not made a significant reduction in greenhouse gas (GHG) emissions over the previous seven years. Recent mergers helped make U.S. carriers among the largest emitters of carbon dioxide (CO2).
